With the assistance of other members here I got my DM-32 up and running great on analog & digital signals. The supplied antenna does not work well on distant signals so I wanted to use my RH77CA antenna instead. I have a few SMA to BNC adapters on hand and tried them to mate the 77 to my Baofeng. I get virtually no signal. I left the radio on 162.550 MHZ weather which is a powerhouse signal here & receive nothing. I also tried my outside discone antenna with the same result. I then ordered a 2 pack of adapters from Amazon that fit snug on top of the Baofeng & still had virtually no signal. I did notice when I lay the radio on its side where the PTT buttons are that it then seems to receive normally. I find it very frustrating. Having the DM-32 on its side when I’m at home looks odd but it works. Out in the field you will understand why the proper orientation of the radio is a priority. I tried the adapters on other Baofeng radios and have the same problem. I would especially get my external antenna to work with the 32. Anyone else experience this glitch & find a solution to this?

To anyone looking to acquire commercial radio programming software:
Please do not make requests for copies of radio programming software which is sold (or was sold) by the manufacturer for any monetary value. All requests will be deleted and a forum infraction issued. Making a request such as this is attempting to engage in software piracy and this forum cannot be involved or associated with this activity. The same goes for any private transaction via Private Message. Even if you attempt to engage in this activity in PM's we will still enforce the forum rules. Your PM's are not private and the administration has the right to read them if there's a hint to criminal activity.
If you are having trouble legally obtaining software please state so. We do not want any hurt feelings when your vague post is mistaken for a free request. It is YOUR responsibility to properly word your request.
To obtain Motorola software see the Sticky in the Motorola forum.
The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). Please use Google or some other search engine to find a dealer that sells the software. Typically each series or individual radio requires its own software package. Often the Kenwood software is less than $100 so don't be a cheapskate; just purchase it.
For M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola).
This is a large and very visible forum. We cannot jeopardize the ability to provide the RadioReference services by allowing this activity to occur. Please respect this.

For what it's worth, I just tried one of my SMA-to-BNC adapters with an RH77 antenna, and it seems fine. I use one of the black adapters with a short SMA female stub.

I have the same problem with some SMA aftermarket antennas not making contact. It seems to be the diameter of the center conductor.
I believe you are right. I took a 2 inch piece of solid copper wire and touched it to the centre conductor in the antenna jack and I was getting the weather channel on 162 MHZ at full strength. What I also notice that the rubber ducky antenna they supply with the radio doesn’t work either. I had to swap antennas with another Baofeng radio to get it to work. The swap worked for both radios. All of the adapters work perfectly on my Quansheng handheld. I wonder if there is a way to shim an adapter so that it will contact the centre conductor before attaching the antenna?
